London, Nov 14 - "Twilight" stars Robert Pattinson and Kristen Stewart are dating each other, confirms director Catherine Hardwicke.

The actors, who play onscreen lovers in the vampire movie franchise, have repeatedly denied that they are more than friends. But rumours heated up earlier this week when they were pictured holding hands in Paris.

Now their director has let the cat out of the bag, reports imdb. com.

"After I cast him, I told Robert, Don't even think about having a romance with her. She's under 18. You will be arrested. I didn't have a camera in the hotel room. I cannot say (when it happened). But in terms of what Kristen told me directly, it didn't happen on the first movie. Nothing crossed the line while on the first film.

"I think it took a long time for Kristen to realise, 'Ok, I've got to give this a go and really try to be with this person'."

Kristen split from her longterm boyfriend actor Michael Angarano earlier this year. (IANS)
